Giant Magnetoresistance of Ni-Co(Cu)/Cu Multilayers Plated from a Citrate Electrolyte

摘要

Electrodeposited multilayers show lower giant magnetoresistance (GMR) than multilayers deposited by sputtering.As electrodeposition is a simple and cheap method to produce multilayers,many researchers are trying to improve GMR of multilayers produced by this method.We report GMR in Ni-Co(Cu)/Cu multilayers electrodeposited from a citrate electrolyte by a potentiostatic two-pulse plating method as a function of the thickness of nonmagnetic and magnetic layers and of the number of interfaces.
